Roofing in Middlesex County, NJ

What Does the Age of Middlesex County's Houses Mean for Their Roofs?

It means many roofs in the county sit on framing that is several decades old and has likely been re-covered more than once, so the condition of what lies under the shingles matters as much as the shingles themselves.

Middlesex County has 319,973 housing units. According to the U.S. Census Bureau's 2024 American Community Survey, 54.9% of them were built before 1980, 10.3% were built in 1939 or earlier, and the median home was built in 1975.

A house built in the mid-1970s has had close to fifty years of freeze-thaw cycles, summer heat and wind-driven rain. Over that span, the roof covering is usually the part that gets replaced, while the sheathing boards, rafters, flashing details and attic ventilation often stay original. When the old covering comes off, those hidden parts are finally visible, and that is the moment to decide whether a board is soft, whether a chimney or wall joint was flashed correctly, and whether the attic can breathe.

Older homes also tend to carry additions, dormers and porches from different decades. Every place where a newer roof meets an older one is a joint that has to be flashed and sealed, and those joints are where many leaks in older houses begin. A good inspection looks at each of them rather than only at the main slopes.

Do You Need a Permit to Replace a Roof in Middlesex County, and Who Issues It?

Usually not, if the job is only a new roof covering on a detached one- or two-family house. The New Jersey Uniform Construction Code lists replacing the roof covering on those homes as ordinary maintenance under N.J.A.C. 5:23-2.7, which means no permit, no notice and no inspection.

That exemption covers the covering itself. It does not stretch to structural work. Replacing or sistering rafters, cutting in a new skylight or dormer, removing or altering framing, or rebuilding a roof that a fallen tree has broken are changes to the structure, and they go through the construction office before the work begins. The exemption's wording names detached homes, so owners of an attached house such as a townhouse should ask the town before scheduling a tear-off.

In Middlesex County the permit office is the construction office of the municipality where the house stands, not the county. A roof in Edison is handled by the office that serves Edison, one in Piscataway by the office that serves Piscataway, and so on across the county. Every town enforces the same statewide code, so the rule itself does not change from Metuchen to Perth Amboy; what changes is the practical side, such as how applications are filed and inspections booked. The Department of Community Affairs publishes a directory of local construction offices.

Plumbing, electrical and HVAC work must be done by contractors licensed in those trades (a homeowner working on their own single-family home is the exception), and the home improvement contractor's state registration number goes on the permit application. MG Builders' registration number is 13VH08376600.

Should a Leaking Roof Be Repaired or Replaced?

Repair it when the problem is local and the rest of the roof is sound; replace it when failures are spread across the slopes or the covering has reached the end of its life. The answer comes from looking at the whole roof, the attic and the ceilings below, not only at the spot where water showed up.

Water travels. A stain on a bedroom ceiling can start several feet uphill at a vent pipe, a chimney or a valley, run along a rafter and drop where the framing lets it. That is why a repair quote should name the source of the leak, not just the place it appeared, and why a patch over the wrong spot rarely lasts.

What Happens When a Tree or Storm Damages a Roof?

The first job is to stop more water from getting in; the second is to find out how far the damage goes. A limb that punches through shingles can also crack rafters, split sheathing and soak insulation and drywall, and the longer the opening stays exposed, the more of the house gets wet.

On a lot with mature trees, a single storm can put a heavy limb on a roof in minutes. Once the opening is covered, the damaged area should be opened up from inside and out so the framing can be checked. If a rafter or ceiling joist is broken, the repair is structural and goes to the town's construction office before it starts; replacing only the shingles over a broken frame is not a repair.

Water that got inside needs attention on its own timeline. The EPA's guidance on mold says the key to mold control is moisture control, and that water-damaged areas and items should be dried within 24 to 48 hours. Wet insulation, soaked drywall and carpet often cannot be dried in place and have to come out, which is why storm repairs so often turn from a roof job into an interior rebuild as well.

One of the reviews on this page describes exactly that sequence: a roof smashed by a tree, followed by a flooded first floor and basement. Handling the roof, framing, drywall, flooring and finishes under one contractor means one schedule and one person responsible for how the pieces fit together.

1. 1

   Make the opening safe and dry

   Keep people out of rooms under the damage, then cover the hole so rain cannot reach the framing or ceilings.

2. 2

   Document what you see

   Take photos of the roof, the attic and every wet ceiling, wall and floor before anything is removed.

3. 3

   Open up and inspect

   Check rafters, sheathing and ceiling framing around the impact, and trace where the water went inside.

4. 4

   Dry out and remove what cannot be saved

   Dry wet areas quickly and take out soaked insulation, drywall or flooring that will not dry in place.

5. 5

   Rebuild in order

   Framing first, with the town involved if the structure is affected, then sheathing and the new covering, then the interior.

What Should a Written Roofing Proposal Include?

It should describe the whole job in enough detail that two bids can be compared line by line and the finished roof can be checked against the paper. A proposal that only names a shingle color and a total leaves the most important decisions unstated.

The biggest gap in many roofing quotes is what happens under the old covering. Nobody can see the sheathing until the shingles are off, so the proposal should say how damaged boards will be found, how they will be shown to the homeowner, and how replacement will be approved before it is done. The same goes for anything the tear-off reveals in the framing.

How Does a Roof Replacement With MG Builders Work?

It starts with a visit to look at the roof, the attic and any ceilings with stains, and ends with a walk-through after the cleanup. What happens in between depends on what the old roof is hiding, which is why the steps below include a checkpoint after the tear-off.

1. 1

   Inspection and free estimate

   Look at the slopes, flashing, gutters and edges from outside, then at the attic and interior ceilings, and talk through repair versus replacement.

2. 2

   Written proposal

   Put the materials, the flashing and ventilation plan, the approach to damaged sheathing, and any structural or permit work in writing.

3. 3

   Scheduling and protection

   Pick a start date around the weather forecast, then cover landscaping and protect siding, windows and the driveway.

4. 4

   Tear-off and decking check

   Remove the old covering down to the sheathing and show the homeowner any boards or framing that need attention before replacing them.

5. 5

   New roof system

   Install underlayment, edge metal, flashing, the new covering and ventilation, closing up each section so the roof is not left open to rain.

6. 6

   Cleanup and walk-through

   Clear debris and nails from the yard and gutters, then review the finished roof with the homeowner.

Do Lead-Paint Rules Apply to Re-Roofing an Older House?

Only to the parts of the job that disturb paint. Shingles themselves are not painted surfaces, but fascia boards, soffits, rake trim and some older wood siding near the roof edge often are, and those can be cut, pried or replaced during a re-roof.

Under the EPA's Renovation, Repair and Painting Rule, contractors paid to disturb painted surfaces in homes built before 1978 must be certified by the EPA and follow lead-safe work practices. Homeowners can ask any contractor for its EPA firm certification before that work begins.

With a county median build year of 1975, many Middlesex County homes fall before that 1978 line. If the proposal includes replacing or repairing painted trim, ask how that part of the work will be handled; the rule is tied to disturbing painted surfaces, not to the shingles.
